Title: An Improved Warp Knitted Elastic Textile Product
IPC: D04B/
Filed: 1979-12-07
Abstract: An elastic textile product consisting of a warp knitted fabric comprising lengthwise extending chains of meshes e.g. polyester along which extend resiliently stretchable threads 8 e.g. rubber. To prevent the textile product from stretching to such a degree when in use that it is permanently deformed, the resiliently stretchable threads pass through selected meshes in the mesh chains, said meshes positioned at regular intervals corresponding to a multiple of the partition of the mesh rows, from one side of the chain, through the respective mesh and out at the same side of the chain, whereby the stretchable threads become loosely interconnected with these selected meshes, but upon stretching of the fabric, are momentarily clamped to said fabric in said meshes. The chains are connected by non-elastic laid in threads 7, e.g. polyester. <IMAGE>
Patent GB-2045811-A (GB)
Title: Overhead conveyor system for garment processing cabinet
IPC: D06F95/00
Filed: 1980-03-13
Abstract: Garment treatment apparatus include one or more cabinets 1 in which garments carried by supports 104, e.g. hangers, are treated by, for example, spraying and heating. However, to restrict loss of heat or processing medium from the cabinet the entrance 5 and exit 6 from the cabinet should be as narrow but at the same time the cabinet should not be too long. Therefore, the garment supports are passed into and out from the carbinet with the support positioned so that a garment or the support has its narrowest dimension transverse with the direction of entry and exit. Thus if the garment is a jacket, one shoulder leads into the cabinet and the other trails. Once in the cabinet, however, means are provided to change the direction of movement of the support e.g. through 90 DEG , without rotating the support so that a garment on the support may be moved through at least garment processing cabinet part of the cabinet with its narrowest dimension changed with the longitudinal axis of that part of the cabinet. Thus, if the garment is a jacket, its shoulder to shoulder line will be transverse to the cabinet axis or then direction of advance, a number of jackets being treated all being arranged with their shoulder lines parallel to one another in a close packed formation. <IMAGE>

Patent GB-2079066-A (GB)
Title: Trimmable electrical inductors
IPC: H01F17/00
Filed: 1980-09-24
Abstract: Trimming either a thin or thick film inductor located on one surface of an electrically non-conductive substrate 10 is achieved by applying to the opposite surface of the substrate a layer 14 of highly conductive metal or of magnetic material of high resistivity. When a on highly conductive metal e.g. Al, Cu or Ag, is used, the inductance is decreased. Progressively reducing either the thickness or the area of the layer, as by grinding, progressively increases the inductance until all of the metal layer has been removed. When a magnetic layer e.g. ferrite is used, the inductance is increased by an amount dependent on the thickness and the area of the magnetic layer. The substrate may be formed from alumina. <IMAGE>
